a) Three equivalent charges 2.0 micro coulomb each, are held fixed at the three corners of an equilateral triangle of side 5 cm. Determine the Coulomb force experienced at its centre.
b) An electric field of 20N/C exists along the X-axis in space. Measure the potential difference VB-VA where the points A and B are given by (a) A = (0,0) and B = (4,2) metre.
(b) A = (4,2) meter and B=(6,5) metre.
explain and give examples of the two types of current
Q. Show the condition for dispersion without deviation? Q. A thin convex length of focal length 0.1m and a thin concave lens of focal length 0.1m are placed coaxially on contact
Q. State Coulombs law in electrostatics? Coulomb's law declares that the force of attraction or repulsion between two point charges is directly proportional to the product of t
a) The medium separated up into a number of components. Every part is vibrating up and down as a whole. b) All the molecules in single particular segment vibrate in the same med
The power distribute to a 15 watt light bulb in normal operation is 15 watts. In normal operation how greatly energy is delivered to such a bulb in an hour? Feedback:
Transverse Waves: The traveling waves in which particles of the elastic medium vibrate about perpendicular to the direction of propagation of waves are known as transverse wave
you were to walk briefly in space without a spacesuit while far from the Sun (as an astronaut does in the movie 2001 ), you would feel the cold of space --while you radiated energ
Electric Potential: Electric Potential verifies the flow of charge. Its unit is volt, represented as "v".
give some examples of like and unlike parallel forces
